ORTHO Mode
Status bar: the 
button
Hot key: F8
Command line: ORTO
With orthogonalisation mode set on, vector lines and rubber lines for editing can only be drawn in directions parallel to the coordinate axis.
If an angle of a coordinate system is changed, the corresponding ortho mode angle is also changed.
The ORTHO mode has higher priority than the polar tracking mode.
note: You can temporarily switch off the ORTHO mode by pressing and holding the SHIFT button when the command of creation or object editing is running.
